Hi guys, I need your help with this questions:

its for parallel computing in C programming language please!

I am stuck and my mind just stopped working! "metaphoracally".

please guys explain to me the main steps, its in C language only.

thank you so much and appreciate the help in advance!!

NOTE: Write your results up to 4 decimals only (1) Run the parallel Sieve program with 1 core only. You MUST run the program 5 times! Use the following data. Remove all print statement (exce t the 'elapsed time ') Run #1 Run #2 Run # 3 Run #4 Average run time Run #5 0,000,000 Take the average run time to determine the value of (chi). Use the formula given in class! Question: What is ? Explain (2) Redo problem #1 with 2 cores. Run #1 Run #2 Run # 3 Run #4 Run #5 Average run time 10,000,000 Use the average run time, with the value of c from problem #1 to determine the value of (lambda). Use the formula in class Question: What is ? Explain (3) Run the following data using 4 and 8 cores. Calculate their average run time (from your data) and the theoretical run time using the formula given in class (with the values of and from problems 1 and 2 above) 4 cores: Run #1 Run #2 | Run #3 Run #4 Run #5 | Average nin Theoretical time (fromrun time data 50 million 100 million NOTE: Write your results up to 4 decimals only (1) Run the parallel Sieve program with 1 core only.
